Yes, dolphins are mammals and have to come up periodically to breathe air.
Oh yes, dolphins breathe air. They have one nostril, called a blowhole, on the top of their heads.
As dolphins are mammals they breath air like us, humans.
Dolphins don t breath under water. Mammals breath air. Every 15 min they go out of the water to breath
Dolphins are a mammal as they give live birth, suckle their young, and breath air.
So they can breath because they are mammals
No sharks are not mammals. marine mammals include dolphins/whales orcas etc mammals are creatures that breath air and since dolphins and whales have a blowhole, they breath air
Dolphins breath air through their noses, just like other mammals. Their noses are called spouts and are located on top of their heads, so they can breath air while keeping virtually all of their bodies in the water.
Yes. Dolphins surface to breathe through their "blowhole" just like a whale.
They don't. Dolphins and whales breathe air just like we do. They can hold their breath for a long time, but they come up to the surface to breathe.
Dolphins go to the surface because they need air (oxygen) to breath and fish can air (oxygen) from the water.
Yes, dolphins are mammals. Dolphins are endothermic, breath air and nurse their young like all other mammals.
They need them to breathe through. Dolphins, being mammals, have to inhale air and hold their breath underwater.
Dolphins can be drowned by becoming entangled in fishing nets. They are mammals and have to rise to the surface regularly to breath air.
